Description / Abstract:
Differences, where they exist, are shown in Appendix A.
This SAE Standard specifies the dimensional features of S, G, D,
and DV oil control piston ring types.
The normal range for the axial width of oil control rings (2.5
to 8 mm inclusive) is divided into 0.5 or 1.0 increments. In Table
7, dimensions in inch units are given for oil control rings with
axial width 4.75 mm (equal to 3/16 in) for existing
applications.
The requirements of this document apply to oil control rings for
reciprocating internal combustion piston engines up to and
including 200 mm in diameter. They may also be used for piston
rings of compressors working under similar conditions.
Rationale—SAE J2002 is being discontinued
because the content of this standard is also contained in ISO 6625.
Therefore, to eliminate duplication and confusion in coordinating
the standards between ISO and SAE, this document will be
discontinued. The SAE Piston and Ring Standards Committee will now
continue to support ISO in updating the standards as
appropriate.
